Skip to comments.Maybe an Asteroid Didn't Kill the Dinosaurs

When a scientific principle is common knowledge even in grammar school, you know it has long since crossed the line from theory to established fact. That's the case with dinosaur extinction. Some 65 million years ago as we've all come to know an asteroid struck the earth, sending up a cloud that blocked the sun and cooled the planet. That, in turn, wiped out the dinosaurs and made way for the rise of mammals. The suddenness with which so many species vanished after that time always suggested a single cataclysmic event, and the 1978 discovery of a 112-mile, 65-million-year-old crater off the Yucatán Peninsula near the town of Chicxulub seemed to seal the deal.

Darwin Would Have Loved It Now, however, a study in the Journal of the Geological Society throws all that into question. The asteroid impact and dinosaur extinction, say the authors, may not have been simultaneous, instead occurring 300,000 years apart. That's an eyeblink in geologic time, but it's a relevant eyeblink all the same one that occurred at just the right moment in ancient history to send the extinction theory entirely awry.

“I know what caused the death of the dinosaurs, global warming.”
And those Dinosaurs drove humongus SUVs.
They were probably around after the flood,
but a whole bunch of yayhoos in armor, out to prove themselves by killing a “dragon”, exterminated them.
No, ancient global warming was due to all those gigantic dinousaurs, which were largely herbivores, emitting earth-shattering farts. The warming was OK by them, since they were coldblooded, but it ultimately proved to be their undoing. The asteroid set off the gas. KABOOM! That’s where precious gems come from; when the force of the exploding, methane-drenched atmosphere forced dead dinosaur carcasses deep underground, under tremendous pressure. Natural gas was trapped in those carcasses, too, which is why it stinks.

They would have survived on Noah's Ark.
All those dinosaurs would have sunk Noah’s Ark. Particularly if they went clomping around like Calvin does when he thinks he a dinosaur.
answer: second hand smoke..
Theories are only that and true scientists do their best to disprove them through the scientific method. Something that has been sorely lacking in most discussions of AGW.
From the article...
"So if the Chicxulub asteroid didn't kill the dinosaurs, what did? Paleontologists have advanced all manner of other theories over the years, including the appearance of land bridges that allowed different species to migrate to different continents, bringing with them diseases to which native species hadn't developed immunity. Keller and Addate do not see any reason to stray so far from the prevailing model. Some kind of atmospheric haze might indeed have blocked the sun, making the planet too cold for the dinosaurs it just didn't have to have come from an asteroid. Rather, they say, the source might have been massive volcanoes, like the ones that blew in the Deccan Traps in what is now India at just the right point in history."

the post flood world just wasnt hospitable....plain and simple..unless you believe in secular fairy tales...
This is all wrong. What killed off the dinosaurs is the last generation of dinosaur babies all turned out to be gay.
